Why Won’t the S-Flex 212 Drive Start When Using Remote Start (Terminals 5–6)?

If the S-Flex 212 drive does not start when closing the remote start contact on terminals 5–6, check the following common causes:

Troubleshooting Steps:

1. Verify Remote Mode is Active

   • Ensure the drive is in Remote mode.
   • The LOC (Local) LED should be off. Press the LOC/REM button if needed.

2. Confirm Proper Control Mode and Wiring

   • Make sure the AFC/Bypass switch is set to AFC mode.
   • Verify terminals 5–6 have a dry contact completing the circuit.
   • Ensure the Lower Limit (LL) is set above 0 Hz if no analog speed reference (VIA/VIB) is used.

3. Check Communication Card Settings (if installed)

   • If a communication card is present, confirm these parameters:
     • CNOD = 0 (Terminal control)
     • FNOD = 1 (VIA) or 2 (VIB)
     • F108 = 48 (Force local always active)

4. Inspect Wiring Connections

   • Look for loose or incorrect wiring in the control circuit.

5. Review External Interlocks

   • Check if an end-of-damper circuit or other interlock is preventing the start command.

6. Consult the Installation Manual

   • Refer to the S-Flex 212 wiring diagrams (manual 30072-451-83B) for correct configuration.
